Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of electrical components, and particularly to an operating handle and a circuit breaker. Background Art
[0002] A circuit breaker is a common switching device that can connect or disconnect the circuit controlled by the circuit breaker. The circuit breaker includes an operating handle and a housing. The operating handle is rotatably installed on the housing, and an operator can achieve opening or closing of the circuit breaker by rotating the operating handle.
[0003] The existing operating handle is relatively laborious to use. For this reason, some operating handles with improved structures have emerged, but the improved operating handle has a relatively complex structure and relatively complicated operation steps.
[0004] Therefore, there is an urgent need for an operating handle with a simple structure and convenient operation. Utility Model Content
[0005] The present application provides an operating handle and a circuit breaker, which can make the structure of the operating handle simple and the operation convenient.
[0006] In a first aspect, the present application provides an operating handle applied to a circuit breaker. The circuit breaker includes a housing. The operating handle includes a handle main body and a folding member. The handle main body is rotatably installed on the housing. The handle main body is provided with a receiving cavity, and at least a part of the folding member is located in the receiving cavity. The folding member is rotatably connected to the handle main body. The folding member can rotate relative to the handle main body to be received in the receiving cavity. When the folding member is received in the receiving cavity, the folding member can also rotate in the opposite direction relative to the handle main body to partially expose from the handle main body.
[0007] Through the above solution, first, the operating handle only includes a handle main body and a folding member, and the handle main body is provided with a receiving cavity for receiving the folding member, so that the number of components required for the operating handle is small. Second, the folding member is rotatably connected to the handle main body, and the handle main body is rotatably installed on the housing, so that the connection relationship of the operating handle is relatively simple, and thus the structure of the operating handle is relatively simple. The folding member can rotate relative to the handle main body or in the opposite direction relative to the handle main body, so that the folding member is received in the receiving cavity or partially exposes from the handle main body. When a part of the folding member exposes from the handle main body, an operator can operate the operating handle by grasping the part of the folding member that exposes from the handle main body, thereby making the operation of the operating handle more convenient.
[0008] In a possible design, the folding member includes a first sub-member and a second sub-member, and the first sub-member and the second sub-member are located on opposite sides of the handle main body.
[0009] Through the above solution, the first sub-component and the second sub-component can enable the operator to form a larger contact area when grasping the operation handle, and make the force exerted by the operator on both sides of the handle body more uniform, so that the force on the operation handle is more uniform, thereby reducing the risk of damage to the operation handle during operation and improving the working stability of the operation handle.
[0010] In a possible design, the storage cavity penetrates through the opposite sides of the handle body.
[0011] Through the above solution, this setting method can enable the first sub-component and the second sub-component to be jointly stored in the storage cavity. In addition, the above setting method can form a through cavity inside the handle body to reduce the material consumption of the handle body, thereby reducing the production and processing cost of the handle body.
[0012] In a possible design, the storage cavity includes a first cavity and a second cavity. The first cavity and the second cavity are independent of each other. The first sub-component is rotatably connected to the handle body near the first cavity, and the second sub-component is rotatably connected to the handle body near the second cavity.
[0013] Through the above solution, the first cavity and the second cavity can respectively store the first sub-component and the second sub-component. The independent first cavity and second cavity can prevent the first sub-component and the second sub-component from interfering with each other during the storage state or the rotation process, so that the operation handle can work properly, enabling the circuit breaker to maintain good working stability.
[0014] In a possible design, the rotation center of the folding component is located at a part of the handle body away from the housing.
[0015] Through the above solution, this setting form can prevent the housing from interfering with the folding component during rotation, so that the folding component can work properly and maintain a stable working state, and further enable the operator to complete the operation task normally and stably by using the operation handle.
[0016] In a possible design, the folding component is provided with a grasping part, and the grasping part is arranged at one end of the folding component away from the rotation center.
[0017] Through the above solution, when the folding component is stored in the storage cavity, the grasping part can provide a force application point for the operator to grasp the folding component, so as to facilitate the operator to rotate the folding component to a position exposed from the handle body, thereby facilitating the operator's operation of the operation handle. The setting position of the grasping part enables a longer force arm to be formed between the force application point of the folding component and the rotation center when the operator rotates the folding component by grasping the grasping part, so as to reduce the external force required for the operator to rotate the folding component, thereby enabling the operator to operate more easily and conveniently.
[0018] In a possible design, the grasping part is configured to be convex.
[0019] Through the above solution, the convexity can facilitate the operator's grasping and reduce the grasping difficulty of the grasping part, enabling the operator to quickly complete the operation of the folding part, thereby reducing the operation difficulty of the operating handle and improving the operating efficiency of the operator.
[0020] In a possible design, the folding part is riveted or screwed to the handle body.
[0021] Through the above solution, riveting or screwing connection has the characteristics of simple and convenient installation, can simplify the processing technology of the rotational connection between the folding part and the handle body, and improve the production and processing efficiency of the operating handle.
[0022] In a possible design, the operating handle further includes a locking part, which is installed in the storage cavity and cooperates with the folding part to separate or connect the folding part from the locking part.
[0023] Through the above solution, the cooperation between the locking part and the folding part can keep the folding part in good position stability when it is stored in the storage cavity, avoid large displacement of the folding part in the storage state, reduce the risk of damage to the folding part, and facilitate the storage management of the folding part.
[0024] In a second aspect, the present application provides a circuit breaker, including a housing and the operating handle of the first aspect, and the operating handle is rotatably installed on the housing.
[0025] Through the above solution, the housing can not only provide an installation platform for the operating handle and the internal components of the circuit breaker, but also provide a protection barrier for the operating handle and the internal components of the circuit breaker, so as to play a protective role for the circuit breaker.
[0026] For the circuit breaker provided in the above second aspect and each possible design of the second aspect, the beneficial effects can refer to the beneficial effects brought by the above first aspect and each possible implementation manner of the first aspect, and will not be elaborated here.

[0043] Figure 1 This is a schematic diagram of the overall structure of a circuit breaker provided by an embodiment of the present application.
[0044] As Figure 1 shown, the present application provides a circuit breaker 2, including a housing 21 and an operating handle 1, and the operating handle 1 is rotatably installed on the housing 21.
[0045] A circuit breaker 2 refers to a switching device that can close, carry, and interrupt the current under normal circuit conditions, and can also close, carry, and interrupt the current under abnormal circuit conditions within a specified time.
[0046] The rotational installation form of the operating handle 1 and the housing 21 can be pin connection, socket handle connection, etc.
[0047] The housing 21 can not only provide an installation platform for the operating handle 1 and the internal components of the circuit breaker 2, but also provide a protection barrier for the operating handle 1 and the internal components of the circuit breaker 2, so as to play a protective role for the circuit breaker 2.
[0048] The specific structural form of the operating handle 1 will be introduced in detail below and will not be elaborated here for the time being.
[0049] Specifically, the operating handle 1 can be connected to the actuator inside the circuit breaker 2, and by rotating the operating handle 1, the circuit breaker 2 can be switched to the off state or the on state.
[0050] Figure 2 This is a schematic diagram of the overall structure of an operating handle provided by an embodiment of the present application, Figure 3 This is a schematic diagram of the structure of a handle body provided by an embodiment of the present application.
[0051] Referring to Figures 1 to 3 , the present application provides an operating handle 1, which is applied to a circuit breaker 2. The circuit breaker 2 includes a housing 21. The operating handle 1 includes a handle body 11 and a folding member 12. The handle body 11 is rotatably installed on the housing 21. The handle body 11 is provided with a receiving cavity 111. At least a part of the folding member 12 is located in the receiving cavity 111, and the folding member 12 is rotatably connected to the handle body 11. The folding member 12 can rotate relative to the handle body 11 to be received in the receiving cavity 111. When the folding member 12 is received in the receiving cavity 111, the folding member 12 can also rotate in the opposite direction relative to the handle body 11 to partially expose from the handle body 11.
[0052] The shape of the handle body 11 can be different regular shapes such as cylindrical, prismatic, ellipsoidal cylindrical, square columnar, hexagonal columnar, etc. The regular-shaped handle body 11 is convenient for machining, can reduce the production and processing difficulty of the handle body 11, and simplify the structural form of the handle body 11.
[0053] The handle body 11 can adopt an integrated molding process. Specifically, the handle body 11 can adopt an injection molding process. Since injection molding has the characteristics of being convenient for rapid production, high automation, and high processing accuracy, it can improve the production and processing efficiency and processing accuracy of the operating handle 1, so as to facilitate the popularization and application of the operating handle 1.
[0054] The shape of the folding member 12 can be different regular shapes such as cylindrical, prismatic, elliptical cylindrical, square cylindrical, hexagonal cylindrical, etc., or different irregular shapes such as cloud-shaped.
[0055] The rotational mounting method of the handle body 11 and the housing 21 can be pin connection, sleeve handle connection, etc.
[0056] Taking the illustrated folding member 12 as an example, the folding member 12 includes opposite first and second ends. Among them, the first end of the folding member 12 is rotatably connected to the handle body 11, and the second end of the folding member 12 is a free end. When the folding member 12 rotates relative to the handle body 11, the second end will be partially or fully located in the storage cavity 111. When the folding member 12 rotates relative to the handle body 11, the second end will move to be completely exposed from the storage cavity 111.
[0057] The rotational connection method between the folding member 12 and the handle body 11 can be shaft connection, hinge connection, universal joint connection, rivet connection, etc. In actual production applications, the rotational connection method between the folding member 12 and the handle body 11 can be rivet connection.
[0058] Specifically, corresponding connection holes are provided on the first end of the folding member 12 and the handle body 11, and after the rivet passes through the connection holes on the first end and the handle body 11, riveting is performed. Riveting has the characteristics of good tightness and convenient installation, which can simplify the processing technology of the rotational connection between the folding member 12 and the handle body 11 and improve the production and processing efficiency of the operating handle 1.
[0059] In another alternative embodiment, the folding member 12 is screwed to the handle body 11. Screwing connection has the characteristics of simple installation operation and detachable. On the one hand, it can reduce the production and processing difficulty of the operating handle 1 to improve the production and processing efficiency of the operating handle 1, and on the other hand, it can solve the faults caused by some screws by quickly replacing the screws, which is convenient for the later maintenance operation of the operating handle 1.
[0060] Among them, the handle body 11 is provided with a storage cavity 111, and the connection hole of the handle body 11 communicates with the storage cavity 111. Since the first end is rotatably connected to the handle body 11, during the rotation of the folding member 12, the partial structure where the first end is rotatably connected to the handle body 11 will always be located within the storage cavity 111. Therefore, during the rotation of the folding member 12, part of the folding member 12 will always be located within the storage cavity 111. That is, at least part of the folding member 12 is located within the storage cavity 111.
[0061] Based on the foregoing description, when the folding member 12 is rotatably connected to the handle body 11, the connection area between the handle body 11 and the folding member 12 is within the range of the storage cavity 111.
[0062] The first end of the folding member 12 is rotatably connected to the handle body 11, and the second end of the folding member 12 is a free end. When the folding member 12 is received in the storage cavity 111, the folding member 12 can also rotate in the opposite direction relative to the handle body 11 to partially expose from the handle body 11.
[0063] Partially exposing from the handle body 11 means that during the rotation of the folding member 12, the second end will first move from the storage cavity 111 to outside the storage cavity 111, so that the folding member 12 is partially exposed from the handle body 11. This setting enables the operator to operate the operating handle 1 by grasping the part of the folding member 12 that is exposed from the handle body 11.
[0064] In the embodiment of the present application, first, the operating handle 1 only includes the handle body 11 and the folding member 12, and the handle body 11 is provided with a storage cavity 111 for receiving the folding member 12, so that the number of parts required for the operating handle 1 is small. Second, the folding member 12 is rotatably connected to the handle body 11, and the handle body 11 is rotatably installed on the housing 21, so that the connection relationship of the operating handle 1 is relatively simple, and thus the structure of the operating handle 1 is relatively simple. The folding member 12 can rotate relative to the handle body 11 or in the opposite direction relative to the handle body 11, so that the folding member 12 is received in the storage cavity 111 or partially exposed from the handle body 11. When the folding member 12 is partially exposed from the handle body 11, the operator can operate the operating handle 1 by grasping the part of the folding member 12 that is exposed from the handle body 11, thereby making the operation of the operating handle 1 more convenient.
[0065] Since the storage cavity 111 is used to receive the folding member 12, an opening communicating with the storage cavity 111 is provided on the handle body 11, so that the part of the folding member 12 located outside the storage cavity 111 can be received in the storage cavity 111 through the opening.
[0066] In actual production applications, when the folding member 12 is partially exposed from the handle body 11, a non-zero included angle will be formed between the side of the handle body 11 provided with the opening and the side of the folding member 12 facing the storage cavity 111.
[0067] The non-zero angle is generally less than or equal to 90°, and the non-zero angle can be customized according to the actual production design requirements. Specifically, the non-zero angle can be 45°, 60°, 90°, etc.
[0068] Therefore, when the folding member 12 is unfolded, the side surface of the handle body 11 with an opening and the side surface of the folding member 12 facing the storage cavity 111 can be in a vertical state or in a relatively inclined state.
[0069] Figure 4 It is a schematic structural diagram provided by an embodiment of the present application in which both the first sub-member and the second sub-member are exposed from the handle body.
[0070] See Figure 4 , in an alternative embodiment, the folding member 12 includes a first sub-member 121 and a second sub-member 122, and the first sub-member 121 and the second sub-member 122 are located on opposite sides of the handle body 11.
[0071] The shapes of the first sub-member 121 and the second sub-member 122 can be different regular shapes such as cylindrical, prismatic, elliptical cylindrical, square columnar, hexagonal columnar, etc., or different irregular shapes such as cloud-shaped.
[0072] The first sub-member 121 and the second sub-member 122 can enable the operator to form a larger contact area when grasping the operating handle 1, and make the force exerted by the operator on both sides of the handle body 11 more uniform, so that the force on the operating handle 1 is more uniform, thereby reducing the risk of damage to the operating handle 1 during operation and improving the working stability of the operating handle 1.
[0073] Taking the handle body 11 as a square column as an example, there are 5 surfaces formed in the area of the handle body 11 away from the housing 21, and two groups of symmetrical side surfaces among the four surfaces. Among them, the opposite sides of the handle body 11 refer to any group of symmetrical side surfaces in the handle body 11.
[0074] Specifically, the first ends of both the first sub-member 121 and the second sub-member 122 are rotatably connected to the handle body 11, and the second ends of both the first sub-member 121 and the second sub-member 122 are free ends.
[0075] When the first sub-member 121 and the second sub-member 122 are located on opposite sides of the handle body 11, the directions of rotation of the first sub-member 121 and the second sub-member 122 when being rotated and stored in the storage cavity 111 are opposite, and the directions of rotation of the first sub-member 121 and the second sub-member 122 when being rotated and unfolded for standby are also opposite.
[0076] Exemplarily, taking the operating handle 1 in accordance with Figure 4Taking the orientation placement as an example, if the direction of the first sub-component 121 rotating to be received in the receiving cavity 111 is counterclockwise, then the direction of the second sub-component 122 rotating to be received in the receiving cavity 111 is clockwise. If the direction of the first sub-component 121 rotating to be deployed for standby is clockwise, then the direction of the second sub-component 122 rotating to be deployed for standby is counterclockwise.
[0077] In an alternative embodiment, the receiving cavity 111 penetrates through opposite sides of the handle body 11.
[0078] This arrangement enables the opposite sides of the handle body 11 to respectively form a first receiving opening and a second receiving opening that communicate with the receiving cavity 111.
[0079] Continuing to take the operation handle 1 placed in the Figure 4 orientation as an example, when the first sub-component 121 is in the deployed state, the first sub-component 121 rotates counterclockwise, and the part of the first sub-component 121 located outside the receiving cavity 111 can be received in the receiving cavity 111 through the first receiving opening. Similarly, the second sub-component 122 rotates clockwise, and the part of the second sub-component 122 located outside the receiving cavity 111 can be received in the receiving cavity 111 through the second receiving opening.
[0080] When the first sub-component 121 is in the received state, the first sub-component 121 rotates clockwise, and the part of the first sub-component 121 located inside the receiving cavity 111 can be partially deployed outside the receiving cavity 111 through the first receiving opening. Similarly, the second sub-component 122 rotates counterclockwise, and the part of the second sub-component 122 located inside the receiving cavity 111 can be partially deployed outside the receiving cavity 111 through the second receiving opening.
[0081] The arrangement where the receiving cavity 111 penetrates through opposite sides of the handle body 11 enables the first sub-component 121 and the second sub-component 122 to be received in the same receiving cavity 111. In addition, the above arrangement enables a through cavity to be formed inside the handle body 11, so as to reduce the material consumption of the handle body 11, thereby reducing the production and processing cost of the handle body 11.
[0082] Figure 5 This is a schematic structural diagram of a handle body provided by an embodiment of the present application in a sectional view, Figure 6 This is a schematic structural diagram of an operation handle provided by an embodiment of the present application in a sectional view.
[0083] Such as Figure 5 and Figure 6As shown, in an alternative embodiment, the storage cavity 111 includes a first cavity 1111 and a second cavity 1112. The first cavity 1111 and the second cavity 1112 are independent of each other. The first sub-component 121 is rotatably connected to the handle body 11 near the first cavity 1111, and the second sub-component 122 is rotatably connected to the handle body 11 near the second cavity 1112.
[0084] On opposite sides of the handle body 11, a first opening and a second opening can be respectively formed. Among them, the first opening communicates with the first cavity 1111, and the second opening communicates with the second cavity 1112.
[0085] Taking the operation handle 1 placed in the Figure 4 orientation as an example, when the first sub-component 121 is in the deployed state, the first sub-component 121 rotates counterclockwise, and the part of the first sub-component 121 located outside the storage cavity 111 can be received into the first cavity 1111 through the first opening. Similarly, the second sub-component 122 rotates clockwise, and the part of the second sub-component 122 located outside the second cavity 11112 can be received into the second cavity 11112 through the second opening.
[0086] When the first sub-component 121 is in the stored state, the first sub-component 121 rotates clockwise, and the part of the first sub-component 121 located inside the first cavity 1111 can be partially deployed outside the first cavity 1111 through the first opening. Similarly, the second sub-component 122 rotates counterclockwise, and the part of the second sub-component 122 located inside the second cavity 11112 can be partially deployed outside the second cavity 11112 through the second opening.
[0087] The first cavity 1111 and the second cavity 1112 can respectively store the first sub-component 121 and the second sub-component 122. The independent first cavity 1111 and second cavity 1112 can prevent interference between the first sub-component 121 and the second sub-component 122 in the stored state or during rotation, so that the operation handle 1 can work properly, enabling the circuit breaker 2 to maintain good working stability.
[0088] In some embodiments, the rotation center of the folding member 12 is located at a part of the handle body 11 away from the housing 21. This setting can prevent the housing 21 from interfering with the folding member 12 during rotation, enabling the folding member 12 to work properly and maintain a stable working state, and further enabling the operator to complete the operation task normally and stably using the operation handle 1.
[0089] When the folding member 12 and the handle body 11 are rotatably connected by riveting, the rotation center of the folding member 12 is located at the rivet installation position.
[0090] Figure 7 This is a schematic structural diagram of a folding member provided by an embodiment of the present application.
[0091] Combined with Figure 2 and Figure 7 , the folding member 12 may be provided with a grasping portion 123, and the grasping portion 123 is provided at an end of the folding member 12 away from the rotation center.
[0092] When the folding member 12 is received in the receiving cavity 111, the grasping portion 123 can provide a force application point for an operator to grasp the folding member 12, so as to facilitate the operator to rotate the folding member 12 to the unfolded state, thereby facilitating the operation of the operating handle 1 by the operator.
[0093] The shape of the grasping portion 123 may be different regular shapes such as a rectangle, a circle, a triangle, etc., or may be an irregular shape such as an arc shape, a cloud shape, etc. In actual production applications, the shape of the grasping portion 123 may be selected as a graph with a relatively simple structure. On the premise of not affecting the use performance of the grasping portion 123, the production and processing procedures of the grasping portion 123 are simplified, so as to reduce the production and processing cost of the grasping portion 123 and improve the production and processing efficiency of the grasping portion 123.
[0094] When the operator rotates the folding member 12 by grasping the grasping portion 123, the force application point between the folding member 12 and the rotation center can form a longer force arm, so as to reduce the external force required for the operator to rotate the folding member 12, thereby enabling the operator to operate more easily and conveniently.
[0095] In an alternative embodiment, the grasping portion 123 is configured as a protrusion.
[0096] The shape of the protrusion may be different regular shapes such as a rectangle, a circle, a triangle, etc., or may be an irregular shape such as an arc shape, a cloud shape, etc. In actual production applications, the shape of the protrusion may be selected as a graph with a relatively simple structure, so that the production and processing procedures of the grasping portion 123 can be simplified on the premise of not affecting the use performance of the grasping portion 123, so as to reduce the production and processing cost of the grasping portion 123 and improve the production and processing efficiency of the grasping portion 123.
[0097] The protrusion can facilitate the grasping of the operator and reduce the grasping difficulty of the grasping portion 123, so that the operator can quickly complete the operation of the folding member 12, thereby reducing the operation difficulty of the operating handle 1 and improving the operation efficiency of the operator.
[0098] In some embodiments, the operating handle 1 further includes a locking member (not shown in the figure), the locking member is installed in the receiving cavity 111, and the locking member cooperates with the folding member 12 to separate or connect the folding member 12 from the locking member.
[0099] The way the locking member cooperates with the folding member 12 can keep the folding member 12 in good position stability when it is received in the receiving cavity 111, avoid large displacement of the folding member 12 in the received state, and reduce the risk of damage to the folding member 12.
[0100] The specific form of the locking member can be a press-type elastic self-locking mechanism, a snap-in locking mechanism, etc.
[0101] In an alternative embodiment, when the locking member is a press-type elastic self-locking mechanism, an elastic element, a locking element and a guiding structure need to be provided in the receiving cavity 111. Among them, the elastic element can be a spring, a spring sheet, etc., and the locking element can be a ratchet wheel, a cam, a lock catch, etc.
[0102] When the folding member 12 can rotate relative to the handle body 11 in the first direction, the operator presses the folding member 12, and the locking element cooperates with the guiding structure to enter the locking position, so that the folding member 12 is received in the receiving cavity 111.
[0103] When the folding member 12 is received in the receiving cavity 111, the operator presses the folding member 12, the locking element disengages from the locking position, the locking element resets to the unlocked state under the action of the elastic element, and the folding member 12 pops out of the receiving cavity 111 under the action of the elastic element, so as to facilitate the operator to grasp and perform subsequent operations.
